[Resolvido] Fatal error: Uncaught exception 'Zend_File_Transf

Olá!

Estou com um problema no upload.

Meu código é o seguinte:

 $nomeArq = "teste_.jpg";

 //Upload do Thumb
 $dirpaiProjetos = "../../_content/images/projetos/";
 $adapter = new Zend_File_Transfer_Adapter_Http();
 $nomeArq = "teste.jpg";

 $adapter->addFilter( "Rename",
 array( "target" => $dirpaiProjetos.$nomeArq,
 "overwrite" => true ),
 "nameInputFile_opicional"
 );

 if (!$adapter->receive())
 {
 $messages = $adapter->getMessages();
 }
 $upload = new Zend_File_Transfer();
 $upload->receive();
 //Returns the file names from all files
 $nomeArq = $upload->getFileName();
 //Retorna o mimetype do arquivo (Se é jpeg, gif, pdf, etc)
 $tipoArq= $upload->getMimeType('uploadedfile');

E o erro que dá é:

Fatal error: Uncaught exception 'Zend_File_Transfer_Exception' with message 'Implementation in progress' in C:\xampp\php\PEAR\Zend\File\Transfer.php:40 Stack trace: #0 C:\xampp\htdocs\ZF\dascanoas\application\controllers\ProjetosController.php(194): Zend_File_Transfer->__construct() #1 C:\xampp\php\PEAR\Zend\Controller\Action.php(513): ProjetosController->acoesAction() #2 C:\xampp\php\PEAR\Zend\Controller\Dispatcher\Standard.php(289): Zend_Controller_Action->dispatch('acoesAction') #3 C:\xampp\php\PEAR\Zend\Controller\Front.php(946): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #4 C:\xampp\htdocs\ZF\dascanoas\index.php(168): Zend_Controller_Front->dispatch() #5 {main} thrown in C:\xampp\php\PEAR\Zend\File\Transfer.php on line 40

Podem me ajudar, por favor?

Obrigada!

Luka.
